Opnion paragraph

This essay is about dogs mustn´t be in parks. Last week I saw how a dog beat a child who was playing football with his friends, the dog was loose , so I think that dogs can´t be loose in parks while there are some children who are playing with their friends or some people who are walking around the park. Therefore in my opinion the best option for all would be doing a specific park where dogs could play and run around the park without disturb people.
